In North America, before the advent of the white man, Native American Turok and his young friend Andar are out hunting when they find and venture into a cave system. After many trials, they find a lost world, as beautiful as it is deadly. In this jungle, dinosaurs and other pre-historic creatures still live side by side!

Exploring the pre-historic jungle, Turok and Andar come across a tribe of cavemen, who naturally are suspicious. Turok is able to win their favor by showing them how they can use arrows with poisonous tips to hunt prey and kill hostile dinosaurs
